To all evhom'z't may concernrv a Be 7 it known that I ALNDREW ENGLE acitiZen ofithe United States ofAmerica,

and a resident of Mound Prairie township, Jasper coimty, Iowa, 'hiI'VBHIIlVBDtEd a new and useful Process of Disposlng' ofNVaste Products and Conservnig Chemical Gons't tuents Thereof, of {which the iollowmg is a specification.

The object of this invention is to-provide an improved process ormethod oi: disposing of waste products such as night-soil, garbage, W6dS,l dead animals and similar or; associated rubbish usually gathered and re,

moved from cities and towns, and conserving and utihzlng chemical constituents thereof such as nitrates and ammonia.

My invention consists in the process or method hereinafter described and claimed.

In carrying out my improved process I may employ means and devices, oneembodiment of which isillustrated by the accompanying drawing, including i V Figure 1, a side elevation, partly in section; Fig. 2, a plan, partlyin section; and Fig.8, a front elevatiompartly in section. In the "construction of the means employed, the numeral 10 designatesya. container, liousing,wvault, structure or building, of generallyrectangular form in plan, provided with end walls and an arched roof. 1 'This structure preferably is composed or built up of concreteyeither monolithic or blocks, but for reasons hereinafter mentioned it may be found desirableto construct it of unbalced clay or sundried bricks such as adobe. However the substance or the structure 10 is not immediately important, other acharacteristics and the use of said structure commanding principal attention.

The housing 10 may be of: any desired di-, mensions; but in this connection attention p I Spekiifi cati on of Letters Patent. Patented F 1 1( 192() Application fil ed December 2, 1918. Serial No. 26 1 975. 1

and said cage is open at its top and sur- 1 rounds the manholes in the 10OTE;O1: the

structure. The spacing of the cage from the walls of the structure preferably is suilicient for the passing or travel of a manbetween them,

in any suitable locationsuch as on one end portion of the structure 10, and a discharge pipe 16, preferably controlled bya valve 17,

p A series of air-supply pipes 14;, in any desired number, 1s mounted through. one "wall of the housnig 10 andextends withln communicates at one end with the interior of the upper portion of the structure 10 and isrecurved and communicates at theother end with the interior of the container 15.

The terminal end of the pipe 16 preferably is submerged in a liquid, such as sulfuric acid, within the container 15. a A furnace is located adjacent tothestructure 10 and is provided with a fire-box 18, gratel?) and chimney 20. iIn thegrate 19 a fire is main- *tainedat times and theiuel employed pref? erably is high in sulfur. content and may be largely composed of sul'lt'ur balls- Communh cation isprovided between the fire-box 18 and the interior of the structure 10, such as by a box 21, and said communication is controlled by a valve or damper 22.

In carrying out my improved process with the means above described, the cage 13 is filled, through the man holes, with the available waste products and refuse, and lime, preferably in solution with water, is applied to the mass in the cage in proportions suflicient to limit acid developmentand for disinfecting purposes therein. After 7 the cage is filled, the man-holes are covered and the mass allowed to rest to establish putrefaction, then air ispumped or introduced under pressure to the mass through the pipes let to the end of thoroughly aerating and ventilating the massl' In passing through the mass, the air becomes saturated with ammonia and carries said ammonia out of the structure in either-of two ways, viz., through the pipe 16 and bath in the container 15 to the end of depositing the ammoniain" said bath, or, through thefirebox 18 tothe end of comminglingsaid ammonia with the sulfur fumes and depositing iflvvith"the-carbon from the fuel'in a soot as indicatedby-the" deposit-23 in Fig. 1.

Sometimes it is, desirable to utilize the drle'dmass-as a fertllizer on land surround in'g-or contiguous to the structure, and it is convenientancleconomical to make the Walls and roof of the structure of sundried clayj ln' order, that the structure may be broken down and connningled' w'ith' the dried mass a'ndthus add-bulk and soil elements-to the-fertilizer; -Insuch condition the clay-component30ftl1e structure also car-' ries into the 'resultant composition a quantityofabsorbed ammonia; Various bacteria useful in'the' development of plant life are,

Any mineral objects contained in the rub bish or waste products are ignored in this operation.-

I claim as my invention-- 1; i iirimproved process of disposing of waste products and conserving chemical constituents thereof, which consists in confining the waste products in mass,and aerating 'saidmas's until the same is dried;

2. An improved process of disposing of waste products andconserving chemical constituents thereof, which consists in confining wasteproducts in mass, passing currents of air through said inass'nntil the mass' is dried and subjecting said currents of air to ammonia-collecting or precipitating media.

3. An improved process of disposing of waste product's'and conserving chemical constituents thereof, which-consists in confining waste products in mass, space beingprovided for free circulation of air around the mass and between'said mass and the confining- -v medium, passing currents of air through said mass until the mass is dried,

and subjecting said air currents to {UH- monia collecting or precipitating media after they have traversed the mass;
